Effects of Grinding Parameters on Creep Feed Grinding
Advanced Materials Research, 2013Creep feed grinding can obtain an excellent grinding performance for its creep feed with high depth of cutting. However the large contact length and large feed result in large amount of heat accumulating in working zone and cause burn on workpiece surface.

Heat transfer model for creep-feed grinding
Journal of Materials Processing Technology, 2005Abstract A heat diffusion-free model based on the assumption of high Peclet number is used to describe the problem of heat transfer in a creep-feed grinding process. The model uses the basic analysis of a moving heat source. Calculation of temperature in the very near region surrounding the grinding wheel grits is shown.

On the kinematics of creep feed grinding
Journal of Machinery Manufacture and Reliability, 2007We consider kinematic dependences of creep feed grinding. We give an analytical model of this process and formulas that relate the area of a nominal section removed during one turn of the grinding disk and the arc length of the contact during grinding stages.

Creep Feed Grinding Of Advanced Ceramics
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 1992Experimental investigation of creep feed grinding of ceramics and their advanced composites is described. Among silicon carbide, zirconia, alumina and silicon nitride, the latter was found to be the most difficult to grind ceramic. Fibre-reinforced silicon nitride was ground in three directions to the fibre.

Pulse Dressing in Creep Feed Grinding
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 1989Machining of the roots and shrouds of turbine blades is normally performed by continuous dress creep feed grinding. In this process, the grinding wheel is continuously dressed during the grinding operation, maintaining constant grinding forces and form accuracy. However, continuous-dressing has incurred higher wheel usage.

The role of cooling in creep feed grinding
The International Journal of Advanced Manufacturing Technology, 1990This paper concerns the thermal aspects of creep feed grinding, as contrasted to conventional grinding. The importance of adequate cooling in creep feed grinding is well known. Without cooling, the grinding temperature in creep feed grinding would be higher than in conventional grinding.

On the study of creep feed grinding of alumina
International Journal of Machine Tools and Manufacture, 1994Abstract Several issues involved in creep feed grinding of alumina with diamond wheels were studied. Influences of variables on responses were investigated. Off-line optimization was performed by formulating the grinding process as a multi-objective nonlinear mixed integer problem. The dominant mechanism of material removal was determined.

Creep-Feed Grinding Wheel Development for Safely Grinding Aerospace Alloys
Journal of Materials Engineering and Performance, 2021Creep-feed grinding wheels have been associated with advances in processing difficult-to-cut materials used in the aerospace industry for many years. Since the late 1960s, the development of grinding wheels used for creep-feed grinding (CFG) operations and high-efficiency deep grinding (HEDG) operations has placed great responsibility on grinding wheel

1986
Creep-feed grinding was developed in Europe in the late 1950s; since then it has been used in an ever-increasing number of applications, particularly in the aerospace industry. Creep-feed grinding in the United States, however, did not enjoy the same success initially, as it appeared that the process was employed using incorrect grinding wheel grades ...

A Thermal Model Covering Pendulum Grinding and Creep Feed Grinding
CIRP Annals, 1983In 1980 P.G. Werner achieved a major step in explaining the low temperature observed in creep feed grinding by proposing a special mathematical model, however insisting on the discrepancies with respect, to the classical case of pendulum grinding. In this contribution the authors show that the formulas for the temperature computation developed by ...
